kernel: Activate CONFIG_HARDENED_USERCOPY for all targets
This activates CONFIG_HARDENED_USERCOPY for the remaining targets. This
adds additional checks in the copy_from_user() and copy_to_user()
functions.
This was not activated for ARCHS38 before because of a bug in the Linux
kernel 5.4 till 5.14, which as fixed and is described here:
https://github.com/foss-for-synopsys-dwc-arc-processors/linux/issues/15
I do not know why this was deactivated for mt7629 and rockchip.
